I got a set of GSX-R camshafts from RapidRay on the fourms here for my gs750 and I am wondering if I should put in some aftermarket valve springs? The cams are .350 intake and .330 exhaust if that helps? I am placing an order from GS Zone for a few other parts and wondering if I should get some APE springs?

I would go with the stock springs for a street bike, HD springs usually end up requiring hardened cam followers (rocker arms) maybe even a top end oiling kit Just don't go wild on redline. RacingJake may have some other ideas for you -
I've ran G4 cams with 355 lift on a 1100 head with stock valves springs. Just make sure you have enough valve to piston clearance, at least 60 thou on the intake side.1166cc 1/8 ET 6.09@111.88

Stock 1100 springs only have 30 lbs of seat pressure. You can run our VS1100S springs for years in a street motor without welded rockers.
